Application filed Au ust 21,1922. Serial 110,583,081.

My invention relates more particularlyto that type of window-in which the sash is mounted for pivotal and sliding movement, rather than vertical reciprocatory movement, and among the objects of my inven. tion are to improve upon the construction ofsuch a window so that the sashes may be opened so as to give complete ventilation or partial ventilation; to so improve upon the construction of a window of this type that the sashes maybe completely reversed for washing or reglazing; to provide means preferably including springs for assisting in, the adjustment of'the sashes, and counterbalancing the weight thereof; to provide an improved trackand shoe, which. will result in, improved action; to provide means for concealing from view the track; to pro- "vide an improved weather-seal for preventing wind and water from passing around the sashes into the room; and such further objects, advantages and capabilities as will hereinafter more fully appear.

My invention further resides in the combination, construction and arrangement of parts illustrated in the accompanying drawings, and while I have shown therein a preferred embodiment, I desire the same to be+ understood as illustrative only and not as limiting my invention.

In the drawings annexed hereto and forming a part hereof Fig. 1 is a perspective view showing my invention, in which the two window sashes are partly opened to permit partial ventilation and at the same time provide an awning for the window space;

' Fig. 2 is a broken perspective view showing the relationship of the track and shoe;

Fig. 3 is a fragmentary horizontal section through the sash, frame and trackway, showing the relationship of these parts and the shoe;

Fig. 4 is a sectional elevation showing the sashes closed and, in dotted lines, in opened position as illustrated in Fig. 1; and

Fig. 5 is a vertical sectional elevation of a window in which the sashes are arranged in vertical a-linement.

Referring more in detail to the annexed drawings, numeral 1 denotes a window frame, and 2 and 3 the upper and lower sashes respectively. Pivotally connected to the frame 1 at 4 and 5 are supporting or brace arms 6. These arms are pivotally connected to t liesashes Qand 3 at 7 and will, therefore, permit the sashes to lnove bodily with respect to the frame as well as have pivotal motion with respect thereto.

Pivoted near the upper edges of'the sashes 2 and 3 are shoes'8having each a body portion folded longitudinally as at 9, and

an attaching portion "10 offset transverselyand laterally as shown more clearly in Figs. I 2 and 3. These shoes are pivoted: at 11 to the lateral edges of the sashes, near the upper edges thereof. A trackway comprising a longitudinally foldedbody portion 12,an'd attaching portion 13, cooperates with the shoe'S to permit appropriate movements of the respective sash and assist in sustaining it i terbalances for the sashes, and thus govern the action of the parts so that the sashes may be moved from closed to open positions and reversely with but little effort on the part of the operator.

If the sashes are arranged in vertical alinement as shown in Fig. 5 the tracks may be straight as here shown, but if the sashes are arranged in oflset relation, as shown in Fig. 4, the tracks may be made in two separate sections, but it will probably be found more satisfactory to have an angular shaped track such as shown in Fig. 1.. where the two vertical sections'are connected by a substantially horizontal intermediate section 15. Over the trackway is placed a covering weather-seal 16, which entirely shuts off from view the trackway 12. 13, when the window is closed. This weathenseal is folded at one edge to. provide a flange 17 to cover the edge of the trackway, and is folded at its opposite edge, as at 18, to provide a portion between which and the trackway a flange 19 on the window sash may enter, thus effectually sealing the window against entry of wind and water when the window is closed. Another flange 20 is provided at the outer corner of the window sash to cover the space between the sash and frame, helping to render the same weather proof as well as giving the structure a neater ap pearance when closed. While this construction has been illustrated and described in connection with a metal window sash, it will be understood that it is applicable also to wooden sashes.

It is, of course, understood that the specific description of structure setforth above may be departed from without departing from the spirit of my invention as set forth in this specification and the appended claims.

Having now described my invention,

I claim 1. In a window construction, a trackway adapted to be secured to a window frame, said trackway having attaching and body portions and an inwardly offset guideway, the opening of which is concealed from view when in use.

2. In a window construction, a trackway having an attaching portion for securement to a window frame, a guideway portion laterally offset from said attaching portion, and a body portion connected between said attaching and guideway portions.

3. In a window construct-ion of the character described, a frame, a pair of sashes, supporting arms pivotally secured adjacent one end to the frame and pivotally secured adjacent their opposite ends to the sashes to permit the sashes to be closed or opened to any desired position or reversed so that the normally outer face shall become the inner face, and resilient means connected to the frame and the sashes to assist inturning the sashes and holding them in adjusted positions.

4. In a construction of the character described having a window frame, and a pivoted window sash, the combination of a shoe having an attaching arm and a body portion offset with relation to the arm, a trackway folded longitudinally to form an open guide for the shoe, an arm connecting the frame and sash for relative pivotal movement, said shoe being folded and engaging the fold of the trackway so that the sash is bodily movable with relation to the frame, and a covering for said trackway adapted to conceal the same from view when the window is closed, and said covering being in part spaced from said traclnvay to form a slot of substantially even thickness, and said sash having a'flange to fit into said slot and cooperate with the trackway, and covering to form a weather seal.

In witness whereof. I hereunto subscribe my name to this specification.
